How do I make – setup – a really good site for my paintings using Minimatica

Hi again. As a newbie I have real difficulties in setting my site up in the most presentable and easy to display my paintings. I tried to make different kategories but it didn’t work out right. When I had a drop-down menu with fx. Large paintings, medium paintings  I could no longer see the menu-display because it in this – wonderful them is shown at the buttom of the page and disappears when I activate the drop-down menues. Has anybody a good idea how I can organize my photos of the paintings and have them presented in different galleries in minimatica? Thanks for your help. Anitta
